1. Ceph and Storage Management with
openATTIC
FOSDEM 2017, Brussels, BE
Lenz Grimmer <lgrimmer@suse.com>
Engineering Team Lead
SUSE LINUX GmbH

2. 2
openATTIC – Our Vision
Develop an alternative to proprietary storage management systems
“Traditional” unified storage (NAS/SAN)
Support Ceph for scale-out scenarios
Open Source, backed with professional support and services

3. 3
OpenATTIC – Notable Changes
Removed Enterprise/Community Edition split
• Now fully under the GPLv2
• Removed requirement for CLA
• DCA (Signed-off-by) is all that’s needed to contribute
Public Issue tracker and roadmap (JIRA)
Public pull requests / code reviews on BitBucket
Monthly releases / nightly snapshot builds
Entire code base (backend/UI/Tests/Docs) in one branch
Part of SUSE since November 2016

4. 4
openATTIC – Key Aspects
Focus on data center storage management
• Support both SAN and NAS functionality without limitations
• Ceph support
Fully Open Source (GPLv2)
• No arbitrary functional restrictions
• Low entrance barrier for adoption
Based on standard Linux / OSS tools and frameworks
Multiple Linux distributions (Debian/Ubuntu/Red Hat/SUSE)
• Well-established, mature technology stack
• Broad vendor support (e.g. device drivers)
• Broad user base

5. 5
openATTIC – Open Source Storage Management
• Modern WebUI
• RESTful API (Software-Defined
Storage)
• Unified Storage
– NAS (NFS, CIFS, HTTP)
– SAN (iSCSI, Fibre Channel)
• LVM, XFS, ZFS, Btrfs, ext3/4
• Volume mirroring (DRBD®)
• Multi-node support
• Monitoring (Nagios/Icinga) built-in
• Ceph management & monitoring
• Development sponsored by SUSE

6. 6
openATTIC – Components
Backend
• Python (Django)
• Django REST Framework
• Linux tools for storage management
(LVM, LIO, filesystem utilities, DRBD,
etc.)
• Nagios/Icinga + PNP4Nagios
(Monitoring and Graphing)
• Salt / DeepSea (Ceph deployment &
management)
• Stick around for Jan Fajerski’s talk
about DeepSea at 15:00
Web Frontend
• AngularJS (JS framework)
• Bootstrap (HTML, CSS and JS
framework)
• Uses REST API exclusively
Automated Test Suites
• Python/Django Unit Tests
• REST API Test framework (Gatling)
• WebUI E2E Tests
(Protractor/Jasmine)

10. 10
openATTIC – Storage Management Roadmap
Add DRBD volume mirroring to the WebUI (WIP)
Extend Disk and Storage Pool Management functionality
• Creating/Managing LVM Volume Groups
• Creating/Modifying Btrfs/ZFS Pools (incl. RAID setups)
• Automatic discovery of disks/pools (via udev)
• Disk health monitoring (SMART)
Extend SAN functionality (more iSCSI/FC features)
Public Roadmap on the openATTIC Jira/Wiki to solicit community
feedback

11. 11
openATTIC – Ceph Management Goals
Create a management & monitoring GUI tool
A tool that admins actually want to use
That scales without becoming overwhelming
Still should allow changes to be made elsewhere, without becoming
inconsistent

12. 12
openATTIC – Current Ceph Development Status
Ceph Cluster Status Dashboard (Performance Graphs, Health Status)
Pool management (view/create/delete)
Pool monitoring
Manage EC profiles
RBD management (view/create/delete/map)
RBD monitoring
OSD management (view)
CRUSH map editor
Support for managing multiple Ceph clusters

13. 13
openATTIC – Ceph Development Roadmap
Dashboard improvements (more metrics / graphs)
Task Queue WebUI (WIP)
Deployment, remote configuration / role assignment of Ceph nodes
(via Salt Open & SUSE’S “DeepSea framework)
iSCSI target management
OSD Monitoring/Management
RGW Management (e.g. users, buckets, keys) via RGW Admin Ops
API
Extend Pool Management
CephFS Management / Monitoring
Remote node monitoring (via Salt & collectd)
